Application filed August 23, 1920. Serial No. 405,214.

To all whom it may concern:

Be it known that I, FRED B. KING, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Spring Cushions, of which I declare the following to be a full, clear, Vand exact description.

rIhis invention relates to improvements in spring cushions for use particularly, although not exclusively, 1n automobiles. The present invention may be regarded as an improvement over my co-pending application, Serial Number 305,892, filed J une 21, 1919.

One of the objects, of the invention is the spacing of the spring assembly away from the apron which joins the cushion and the seat base.

Another object is the centering of the lower part of the spring assembly upon the seat base.

Other objects, and objects relating to details of construction and economies of manufacture, will a pear as I proceed with the description of t at embodlment of the invention which, for the purposes of the present application, I have illustrated in the accompanying drawing, in which:

Figure I is a fragmental pers Aective view of a portion of a seat base em odying my invention, and shows the manner of attaching the apron as well as one of the lugs by means of which the centering of the spring assembly is accomplished.

Fi ure II is an elevational view of a comp ete cushion with certain parts broken away and others shown in sectlon in order to more clearl illustrate the invention.

Figure III 1s a plan view of a fragment of the seat base showing the apron' retaining tongues and the centering lugs in their upright positions, that is, in the positions w ic they occupy before the assembling of the parts.

Figure IV is a detail vertical, sectional view of a lower edge of the' structure.

iSimilar reference characters refer to like parts throughout the views.

In the drawing, 10 represents a wire mesh constituting the princi al part of the base of the seat, said mesh eing attached on all four of its sides to a lower border frame 11. The attachment may be effected by any suitable means; that shown in the drawing belng by welding the ends of each wire to the horizontal ortion of the border frame.

The border rame 11 is bent downwardly near its outer edee to form a groove 12, the outer wall 0I which merges into an upstanding flange 13. The groove 12 is formed for the accommodation of the lower edge of the seat apron 14, extending preferably entirely around the structure. A common method of finishing the lower edge of this apron is illustrated in the drawing, namely, the foldin up of the upholstery material on the inside and stitching through the two thicknesses, thereby leaving a loo at the bottom in which is carried a ro wire or cord 15.

A series of tongues 16 are struck up out of the border frame 11, and before assembly of the parts, stand in vertical position at the inner side of the groove 12. When the lower ed e of the apron is in placeyin the groove, t e tongues 16 are bent outwardly and downwardly over the beaded edge of the apron to hold the latter firmly in place.

The u per edge of the apron 14 is also preferab y beaded and is attached by suitable means to the periphery of the upholstering material 17. The latter is attached at its edges to a frame member 18 extending entirely around the cushion. This rigid frame "prevents the cushion from Vspreading or losing its ori inal shape. The filling material 19 is in" material 1 no under-cover being required as the spring assembly when put in place serves to prevent the 'ilhng from escaping.

In the form of seat structure here illustrated, the springs are assembled together in a unit which'is herein termed the spring assembly. It consists of a multiplicity of coil springs 20 retained in pockets formed by stitching transversely at proper intervals the sides of a longitudinally folded strip of cloth 21. Each such strip carries a series of springs suiiicient in number to' extend substantially across the seat. A number of such strips with their pockets illed with ac ed within the upholsteraround the sides and across the top andA bottom of the whole; The periphery o f the spring assembly at its lower edge is preferably beaded and for this purpose may contain a cord or wire 23. U

Now, in order to space the spring assembly from the apron 14 and also for the purpose of centering the spring assembly upon the seat base, lugs 24 are employed. rll`hese extend upwardly from the border frame 11 inwardly of the groove 12 at intervals along all sides of the frame. 'Preferably these lugs are struck up out of the frame itself, and before assembly of the parts with th naar.

stand vertical. However, the upper ends of the lugs may be, and preferably are,

bent inwardl and downwardly after the spring assem ly is in place in order to more closely contact with the latter and hold it against movement in every direction.

In assembling a seat built according to my invention the following procedure may be followed: The cushion cover, including the.

portion 17 and the apron 14, is first attached to the frame member 18. Then the filling 19 is packed in place, the cushion being inverted. Next the spring assembly is mounted withinthe frame member 18, thereby closing the opening within that frame. Then the inverted seat base is placed over the spring assembly and the lugs 24 bent into contact rlhereafter the lower beaded edge of the apron 14 is fitted within the groove 12 of the lower border frame 11 and the ton ues 16 bent into engagement with thebeaed edge of the apron by means of pliers having at least one jaw of a size that will pass through the openings formed in the border frame when the tongues 16 are struck u out of the same. The seat structure is t en complete.

I am aware that the particular embodiment of my invention herein illustrated and 'described is susceptible of considerable variation without departin from the spirit thereof, and therefore I esire to claim my invention broadly as well as specifically as indicated by the appended claims.

What I claim as new and desire to secure by Letters Patent is:

1. In a seat structure, a lower border frame having an inwardly extending flange portion, aspring assembly supported on said ange portion and comprisin a multiplicity of coil sprin s, means forhol ingthe springs together an in proper position relative to ythe load and to each other, and lugs struck up from said border frame and adapted to engage the exterior of said spring assembly and to be bent inwardly into contact therewith to center the latter upon the lower border frame.

2. In a seat structure, a: lower border fr'ame having at its inner periphery a supporting flange portion and having means near its outer periphery for retaining the lower edge of the seat apron, a spring assembly comprising a multiplicity of coil springs on the said ange portion and means for holding the springs together and in proper position relative to the load and to each other, and lugs extending upwardly from an intermediate portion of said border frame for engaging the exterior of said spring assembly and for centering and spacing the same from said apron.

3. In a spring seat, a frame including ahorizontally disposed border portion, tongues extending upwardly from said border portion intermediate its edges, and a unitary seat element comprising a support and a plurality of springs secured thereon, said seat element being insertable upon and supported by the frame independently of said tongues and adapted to be centered upon the frame by the tongues.

4. In a spring seat, a frame including a horizontally disposedy border member, tongues extending upwardly from said border member intermediate its edges, a unitary seat element comprising a support and a plurality of springs secured thereon, said seat element being insertable upon the frame and supported thereby independently of the tongues, said tongues serving to hold the seat element centered upon the frame, and an upholstery covering for said seat element including an apron extending downwardly and secured to said border member.

5. In aspring seat, a frame comprising a horizontally disposed border member and a plurality of transverse connecting members, a seat element comprising a support and a plurality of springs secured thereon, said 4seat element being insertable upon and removable from the frame as a unit and adapted to be supported thereby, and a plurality of tongues extending upwardly from said border member between the edges thereof and adapted to form guides for centering the seat element upon the frame.

6. In a springseat, a spring structure comico prising a plurality of coil springs, a fabric Y a support for said structure comprising a. portion and a series of lugs struck u from border frame and a wire mesh attached said border frame and engaging the eaded thereto, said frame having a fiat inner peedge of said fabric covering to center and rel0 ripheral portion for qarrying said mesh and tain the spring structure thereon.
